## Quick Overview

The speaker details her transition from a tech career to sustainable glass art, highlighting how applying ecological principles like net-zero carbon practices, waste reduction, and habitat restoration (like seagrass planting) to her small glass studio yielded tangible environmental benefits and inspired broader community action.

**Key Points:**
- The speaker transitioned from a full-time tech job to sustainable glass art after becoming deeply connected to nature.
- Her studio now operates on a net-zero carbon goal, achieved by generating its own power via solar/wind and replanting seagrass.
- In 2022, the studio planted 1,600 native trees and shrubs, with 90% being native to Pembrokeshire.
- The speaker cites Roger Fishman's 'Trim Tab' metaphor, emphasizing that small, focused actions create significant change.
- The studio's sustainability efforts resulted in offsetting more carbon than they created, primarily through renewable energy use and waste reduction in glass production.
- In March 2023, the speaker and Neil Wilkin spent a day at a seagrass nursery and later organized an event with the Environment Agency to raise awareness about seagrass restoration.
- The speaker concludes that the fear of failure is less important than the possibility of making a positive difference through small, informed choices.

**Context:** The presentation, occurring at TEDxAberystwyth, is a personal narrative from an artist who shifted her career focus from the tech sector to glass art, driven by a deep connection to nature. She discusses applying rigorous sustainability principles—learned partly from the concept of the 'trim tab'—to her small-scale glassblowing operation to achieve carbon neutrality and promote biodiversity, illustrating how small, consistent actions can lead to significant positive change.

## Detailed Analysis

The speaker recounts leaving her tech career to pursue glass art, a passion ignited by her connection to nature. This transition led her to seriously consider sustainability, prompting her to adopt net-zero carbon practices in her glass studio in Wales. She details specific actions taken since 2021: generating electricity via solar and wind, replacing an oil-fired boiler with an electric one, composting all organics, re-using materials (circular economy), and planting native trees and shrubs (1,600 planted since October 2022). She mentions collaborating with glass artist Neil Wilkin, who redesigned the furnace to improve efficiency and reduce propane use. Inspired by Roger Fishman's 'trim tab' metaphor, she emphasizes that small, focused actions can create large ripples of positive change. She shares data showing that their combined efforts, including offsetting carbon from web hosting and material use, resulted in a net carbon reduction. Furthermore, the speaker partnered with conservation groups and the Environment Agency to raise awareness about seagrass restoration, an effort inspired by a visit to a seagrass nursery. The core message is that the fear of failure should not impede the possibility of making a tangible, positive impact through informed choices.

### Background & Transition

- Deep connection to nature spurred a career change from tech to glass art
- Passion for glass reignited while working in tech
- Moved to a small farm in Wales in 2021 to pursue this.

### Sustainable Studio Practices

- Aiming for net-zero carbon, replacing oil boiler with electric, using solar/wind power, composting all organics, re-purposing waste glass, and employing circular economy principles.

### Biodiversity & Advocacy

- Planted 1,600 native trees/shrubs since Oct 2022; working with marine advocacy groups on seagrass restoration projects; organized an event with the Environment Agency.

### The Trim Tab Concept

- Inspired by Roger Fishman, the speaker stresses that small, strategic actions (like adjusting a rudder's trim tab) lead to large directional changes in both personal life and organizations.

### Results & Impact

- Carbon footprint calculations show they offset more carbon than they create; the seagrass project generated significant community awareness and excitement, selling out an associated event.
